To all whom. it may concern: 4

Be it known that I, LEWIS lmwis, citizen ol the United States, residing at (oluinbus, in the county of Franklin and State of Ohio, have invented certain new and useful Imprm'ements in ater-Motors, of which the following is a specification.

M invention relates to water motors and has or its object the provision of a device of this cl'iaracter constructed in such manner that it may be. very cheaply manufactured and so simply made that but few workin parts are provided, whereby the tendency (ii the motor to get out of order, will be reduced to a minimum.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

in the accom anvin d-rawin s; Fh ure 1 is a vertical section of a motor constructed in accordance wit-h the invention, Fig. .2 is a vertical section upon line x-x of Fig. 1, Fig. I; is a partial side elevation of the motor, and,

' Fig. 4 is a. detail view of a valve hereinafter described.

Like numerals designate corresponding parts in all of the iigures of the drawing.

Referring to the drawing, the numeral 5 designates the base of the motor. Mounted upon this base is a cylinder 6 in which a piston 7 is slidably disposed. This piston is connected to a. iiston rod 8, said piston rod sliding in a stuling box 9 of the usual and well known construction. At its outer end this piston rod is connected to any member to be driven such as a rack 10.

A valve casing 11 is mounted at the front end of the motor, said valve casing having an annular chamber 112 formed therein. 'lhis chamber is in communication through the port 12% with a by-pass l4. 'lhis by-pass communicates with the interior of the cylinder (3 through a port 15. A second port [(5 leads lrom the chamber 12 directly to the forward end of the )istoii.

A valve which is bcst illustrated in Fig. 4 is mounted in the valve 'asing ll. 'lhis valve comprises the disks to and 17 said disks extcnding above. the body portion 1b of the valve and l'orming' an annular channel It) in the periphery-ol thc valve. point about the periphery ol' the valve, this clinlllicl is intcrrnplial by ribs 30 which c.\ lcnd l'rom the body portion is out\\'ardl the outer laws of said ribs lying [lush with At one the peripheries of thc disks to and 17. A port 21 is formed between these ribs and communicates with a chamber 22 formed ccntrnlly within the valve. An inlet port .325 communicates with this chamber 212, said inlet port being tormed in a nozzle 24 which is threaded at 35 into the valve casing 12. A water supply pi )c is adapted to be threaded upon this nozzle.

A valve stem 2o passes through thc-stulling box 27 carried by the valve casing, said stem being preferabbv integral with the valve and the valve turmng with the stem. Secured by a set screw 28 upon the outer end of this valve stem is an upstanding arm .2.) which carries near its outer end a pin 30. l pstanding from the base 5 is a standard 31, upon which an oscillatory member 32 is pivoted as at 33. This member is cut out as at 34 tor the reception of the pin 30. One end of a spring 35 is connected to a screw or rivet 36 which is carried by the oscillatory member 3'2 and the opposite end of said spring is connected to a screw or rivet 37 which is carried by the base 5. An arm 38 projects from the driven member it) toward the cylinder and at the end nearest the cylinder carries a )in 39, this pin traveling bctwecn legs 40 which depend from the. oscillatory member 3;.

The operation of the device is as follows: Water enters through the inlet )ort 23 and with the valve in the position illustrated in Fig. 1, flows through the chamber .22 and out through the iorts .21 and n; to the l'orward end ot the cylinder, driviin the piston toward the right in said ligure. lhccxhaust from the opposite end ol the cylinder is driven out through the port 15. by-pass 14, port 13 and annular channel It) to the exhaust nut 41, from whcncc it may be conducted by suitable piping to any point. .\s the piston moves toward the right. the pin Ii.) strikes the right hand leg 40 in Fig. .l and throws the upper portion of the oscillatory member 3;! to thc lcl't until the right hand wall ol' the cut-ont portion It] strikes against the pin CH). \Yhcn lhc screw or rivcljiu moves past the center 33!, the spring in will act to throw the pin illl quickly to its limit (il lllUYOllltlll pins l'. serving to limit the throw ol' the arms ll) in either dir cti n. When the pin Jill is thrown ovcr to the lcll, the arm .2.) which carries aid pin will ol' coursc likewise be thr u n o r to lllt lcl'l and will turn lhc valve stem .14. and th vulv l bring the ports 16 into alinement with the port 13. \Vater from the chamber 22 will then enter the by-pass 14 and from said bypass will enter the right-hand end of the cylinder in Fig. 1, driving the iston toward the left. Any water containec in the left-hand end of the cylinder will at this time, pass through the ports 16 and into the annular channel 19 and from said annular channel 19 to the exhaust port 41. Durin this movement of the piston toward the left, the pin 39 will engage the lefthand arm 40 and will begin to move said arm toward the left. This will move the upper portion of the oscillatory member 32 toward the right and after the left hand wall of the cut-out portion 34 contacts with the pin and the screw 36 moves over the center, the spring will act to throw the pin quickly toward the right in Fig. 3. This will throw the valve back to the position illustrated in Fig. 1 and the movement of the piston will again be reversed.

From the foregoing description, it will be seen that simple and GlfiClQIlt means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are in tended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

What I claim, is:

A water motor comprising a cylinder, piston, a piston rod, a valve casing, an oscillatory valve mounted in said valve casing, means for conducting fluid under pressure to said valve casing, said valve when turned to one of its limits of movement establishing communication between one end of the cylinder and the interior of the valve casing and when turned to its other limit of movement establishing communication between the opposite end of the cylinder and the valve casing, a valve stem, an arm mounted upon the valve stem, a base, a vertical standard carried by said base, a member pivoted to said standard intermediate its ends, said member being bifurcated below its )ivotal point to form legs and said member having a cut out portion above its pivotal point, a pin carried by said arm and working in said out out por tion, a member carried by the piston rod and engaging said legs to shift said member, stop members for limiting the movement of said legs in each direction and a spring, one end of which is secured to the base and the other end of which is secured to the pivoted member above its pivotal point.

In testimony whereof I affix my signature in presence of two witnesses.
